And, even more remarkably, a very similar story has played out over the past three years, this time about economic policy. Back then, all the important people decided that an unrelated war was an appropriate response to a terrorist attack; three years ago, they all decided that fiscal austerity was the appropriate response to an economic crisis caused by runaway bankers, with the supposedly imminent danger from budget deficits playing the role once played by Saddam’s alleged weapons of mass destruction.
....
So the deficit is not a clear and present danger, spending cuts in a depressed economy are a terrible idea and premature austerity doesn’t make sense even in budgetary terms. Regular readers may find these propositions familiar, since they’re pretty much what I and other progressive economists have been saying all along. But we’re irresponsible hippies. Is Ben Bernanke? (Well, he has a beard.)

Detection and Learning of Floral Electric Fields by Bumblebees
http://www.sciencemag.org/content/early/2013/02/20/science.1230883.full
Insects use several senses to forage, detecting floral cues such as color, shape, pattern, and volatiles. We report a formerly unappreciated sensory modality in bumblebees (Bombus terrestris), detection of floral electric fields. These fields act as floral cues, which are affected by the visit of naturally charged bees. Like visual cues, floral electric fields exhibit variations in pattern and structure, which can be discriminated by bumblebees. We also show that such electric field information contributes to the complex array of floral cues that together improve a pollinator's memory of floral rewards. Because floral electric fields can change within seconds, this sensory modality may facilitate rapid and dynamic communication between flowers and their pollinators.
벌이 꽃에서 식사한 다음에 꽃의 전자기장에 변화가 남긴다는 연군데, 이걸 통해서 벌도 이익을 받지만 (by improve a pollinator's memory of floral rewards) 꽃 입장에선 수분 효율을 높인다는군요.
또 꽃 입장에서 변화시키는 경우도 관찰됐는데, 색깔이나 모양, 향기로도 비슷한 일을 수행하지만 꽃 입장에서 빠르게 변화시킬 수 있는 건 전자기 포텐셜이라 빠른 대화가 가능하다, 그런 얘기.
